The best wireless N laptop card

I'm looking for people's input (first-hand accounts most appreciated) on good n protocol internal laptop card/antenna combinations to stick in my XPS 1730. I don't know if it already has three internal antennas or not, as I currently have an Intel card in there for the G protocol.

Recommendations and links would be nice. I'm looking for the best card to stick in there (reliability/range), so pretend as if price were not an issue.

*Note: I don't want to sound pompous, but I would go around and search through existing threads on the subject, but I'm typing from a dial up machine, and navigating this site is murder on that connection. I need the card to get my lappy back up running on the n network and ditch this old machine. I figured pooling results on the subject in one thread would make it easier to manage than painstakingly open different threads.

 

Intel's 5300 Link wifi card is probably the best there is to offer ATM. Although the 5350 with WiMax is also available, WiMax technology is not quite mature in the US, but if you're planning to travel to other countries where WiMax is readily available, then the 5350 would be the better option.
